FRANK A. room, on CLEVELAND, ontov WALL FORM.

Application filed January 19, 1922. Serial No. 530,349.

To all whom it may concern:

Be it known that I, FRANK A. Focus, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga and State of Ohio, have invented a new and useful Improvement in WVall Forms, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions. I

The present invention relating, as indicated, to wall forms is directed to an improved form for concrete walls which may be readily assembled and taken down and which provides a convenient means for pouring a concrete wall in sections. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims. 1 The annexed drawing and the following description set forth in detail certain structure embodying the invention, such disclosed means constituting, however, but one of various structural forms in which the principle of the invention may be used.

In said annexed drawing Fig. 1 is a side view of my improved form; Fig. 2 is anend view of the same showing two forms mounted in co-operative relation; Fig. 3 is a plan view of the same; Fig. 4 is a side elevation of such form, showing its use for sectional work; and Fig. 5 is a side elevation of a modified type ofthe form.

In constructing concrete walls it is customary to erect two spaced vertical forms which are braced in a suitable manner to provide a channel between them into which the concrete may be poured and held until it has set. In Figs. 1 and 2 I have shown the present form so used, there being two spaced vertical forms or walls 1 and 2 which are connected by meansof removable bolts 3 which serve to maintain these wall forms in proper spaced relation during their use. One form may be supported by braces 40 and the other supported from the first. Each of the walls consists of a series of equidistantly spaced, vertical, composite beams 4-, each of which beams is substantiallv an I-beam in form, and, if made of wood, may consist of a plank 5, at the opposite side of which are secured narrower planks 6, which are flush with one edge 7 of the plank 5. Disposed transversely along the other edge 8 of the plank 5 is a board or strip 9, the projecting portions of this board and the two strips 6, 6, serving as flanges of the I-beam, while the plank 5 acts as the connectingweb or body of the beam.

After these beams have been arranged at equidistant intervals and have been connected along their tops and bottoms by means of temporary strips 10 and 11, they are secured together and spaced by means of the bolts 3 which project through the flanges of the beams. There are a number of these bolts which are arranged in staggered relation throughout the length of the beams and these bolts may be removed to permit of the taking down of the entire structure after use.

The wall proper consists of a series of panels 13., 14, 15, the panel 15 being mounted between the lower ends of the I-beams t and being built up of a series of boards 16 connected together by means of strips 17, the ends of which project beyond the outer edges of the boards 16 and serve to engage behind the projecting ends or flanges of the strip 9 of the I-beams 4. In this way one side of each of the panels is brought level with the outer side of the strip 9 and a smooth, unbroken form surface is presented on the interior of the wall channel.

Afterthe panels have been placed in position'they are locked into place by means of braces 20 which are of suflicient width to fit snugly between the flanges of the I-beam and of sufficient length to extend entirely across the panels and abut against the webs of the adjacent beams. These braces rest upon the strips 17. In taking the form down these braces may be removed by sliding one end upward, as shown at the upper right-hand corner of Fig. 1, until it clears the flange 6, when it may be pulled out and after removal of the brace, the panel may be drawn out.

Walls are sometimes poured in horizontal sections or layers and at other times in vertical portions. lVhere the wall is to be poured along its entire length to a certain height and then additional layers poured also for the entire length, the lower panels may first be placed in position, as shown in Fig. 4, and the wall poured to the top of these panels. As soon as this portion of the wall has set, these panels may be removed and may be replaced at a higher elevation to permit the pouring of the next layer throughout the entire length of the wall and this process may be repeated again to pour the upper third of the wall. If the wall is to be poured in sections along its length, the opening between the two forms may be closed by a temporary panel and the wall may then be poured the entire height for a certain portion of this length. After this concrete has set, the panels, as well as the I-beam-s, may be taken down and ieassembled from the end of the wall onward and the remainder of the wall poured in the same forms.

A modified type of panel may be used with the same supporting beams and braces as the above described type of panel, as shown in Fig. 5, and consists of two vertically arranged rectangular panel units 21 and 22 which span the space between two adjacent beams and are provided with a series of braces 23 which have at one side projecting ends fitting behind the flanges on the members 9 of the I-beams in order to bring the face of these panels flush with the face of the I-beam, that is, with the face of the strip 9. The braces 23 are also provided with extending lugs 24; at their other ends which extend across behind the next adjoining panel unit and assist in positioning and holding these two panel units in the center. When in place the panels are locked by means of braces 25 corresponding with the braces 20 shown in Fig. 1, these braces 25 resting upon the braces or lugs 23 as in the preceding case.

The present form is an extremely simple one to construct, is very convenient to as semble and take down and requires a minimum amount of material.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the structure herein disclosed, provided the means stated by any of the fol lowing claims or the equivalent of such stated means be employed.

1 therefore particularly point out and distinctly claim as my invention 1. In a wall form, the combination of spaced parallel I-beams, mounted in vertical positions, means connecting said beams to maintain them in such relation, panels removably mounted between said I-beanis, said panels having extending lugs engaging against the inner surface of one of the flanges on said beams, and braces extending between said beams, said braces engaging between the flanges of said beams and resting on said lugs on said panels.

2. In a wall form, the combination of spaced parallel I-beanis, panels formed of two units mounted side by side and extending between said I-beams, said units being provided with a series of strips providing extending lugs at either side, certain of said lugs engaging behind the flanges of said beams to maintain said panels flush with the outer surface of said beams, and other of said lugs engaging behind the adjacent edges of said respective units, and means adapted to maintain said units in such relation.

3. In a wall form, the combination of spaced parallel I-beams, panels formed of two units mounted side by side and extending between said I-beams, said units being provided with a series of strips providing extending lugs at either side, certain of said lugs engaging behind the flanges of said beams to maintain said panels flush with the outer surface of said beams, and other of: said lugs engaging behind the adjacent edges of said respective units, and braces extending between said I-beams behind said units, said braces being removably engaged between the flanges on said beams and resting on said strips.

Signed by me, this 5th day of IXTNHl'KJ', 1921.
